A 2.58 kg block slides down a smooth, fric- tionless plane having an inclination of 23º.
The acceleration of gravity is 9.8 m/s.

23°

Find the acceleration of the block.
Answer in units of m/s^2

What is the block’s speed when starting from rest, it has traveled a distance of 3.87m along the incline? Answer in m/s

What is the magnitude of the perpendicular force that the block exerts on the surface of the plane at a distance of 3.87 m down the incline? Answer in Newton’s
